Detailed Description

Example of a sinusoidal density variation plus a constant density.

Parameters: a_gamma - Gamma for polytropic, gamma-law gas a_ambientDensity - Ambient density add to the density sinusoid a_deltaDensity - Mean of the sinusoid a_pressure - If 0, use isentropic pressure if 1, use the constant pressure of 1.0 a_center - Center of the peak of the sinusoid a_velocity - Initial velocity of the gas a_artvisc - Artificial viscosity coefficient

The sine is adjusted so that one period fits in the domain in each direction - assuming the domain is a square (required).

const Real &    a_deltaDensity,
const int &    a_pressure,
const RealVect &    a_center,

Destructor.

Member Function Documentation

void SineIBC::fluxBC (  FArrayBox &    a_F,
const FArrayBox &    a_W,
const FArrayBox &    a_Wextrap,
const int &    a_dir,
const Side::LoHiSide &    a_side,
const Real &    a_time
)  [virtual]
 

Set boundary fluxes.

Implements PhysIBC.

void SineIBC::initialize (  LevelData< FArrayBox > &    a_U )  [virtual]
 

Set up initial conditions.

Implements PhysIBC.

PhysIBC* SineIBC::new_physIBC (    )  [virtual]
 

Factory method - this object is its own factory.

Return a pointer to a new PhysIBC object with m_isDefined = false (i.e., its define() must be called before it is used) and m_isFortranCommonSet set to value of m_isFortranCommonset in the current (factory) object.

Implements PhysIBC.

void SineIBC::setBdrySlopes (  FArrayBox &    a_dW,
const FArrayBox &    a_W,
const int &    a_dir,
const Real &    a_time
)  [virtual]
 

Set boundary slopes.

The boundary slopes in a_dW are already set to one sided difference approximations. If this function doesn't change them they will be used for the slopes at the boundaries.

Implements PhysIBC.

void SineIBC::setFortranCommon (  const Real &    a_gamma,
const Real &    a_ambientDensity,
const Real &    a_deltaDensity,
const int &    a_pressure,
const RealVect &    a_center,
const RealVect &    a_velocity,
const Real &    a_artvisc
) 
 

Sets parameters in a common block used by Fortran routines.

void SineIBC::setFortranCommonSet (    ) 
 

Set the flag m_isFortranCommonSet to true.

Set the flag m_isFortranCommonSet to true so that new IBCs made with new_physIBC() will have this flag set without calling setFortranCommon() (this is a clumsy design and should be improved).
